Guide
Using This Tool
Purpose
Start from capability requirements instead of pin assignments. Use the filter cards to ask for counts of buses, timers, serial blocks, Ethernet classes, memory controllers, and other MCU features.
Close Matches
When enabled, the table adds separate sections for parts missing exactly one or two requirement units. Package filters stay hard constraints and never move parts into close-match sections.
Pinmux Handoff
Every row can open a fresh Pinmux project in a new tab. The handoff pre-enables the first matching concrete peripherals for each active filter, while near-miss rows only enable peripherals that the selected MCU actually has.
